6-62 Motors
1326AB Series Motors
1326AB Torque Plus motors feature a specially engineered housing that
reduces motor length and increases continuous torque ratings. These
high performance, three-phase, brushless, AC, synchronous servo
motors are designed by Allen-Bradley to meet the stringent
requirements of high performance motion systems. This series of
460V, AC servo motors is intended to be used with the Allen-Bradley
1394 Motion Control System.
Each servo motor features:
• Special flux profile permanent magnets engineered by Allen-Bradley to increase servo response.
• A three-phase, sinusoidal-wound stator field for smooth operation at low speeds.
• TENV construction. IP65 is standard when used with the shaft oil seal kit (1326AB-MOD-SSV-xxx. IP67
(-L) option is available.
• An extruded aluminum housing for improved heat transfer.
• 100% continuous-rated output torque at stall (zero rpm).
• A UL Listed insulation system (file #E57948).
• The ability to be vertically mounted at any angle with the shaft up or down.
• A normally closed thermal switch in the motor winding (rated 115V AC/ 24V DC at 1A) that provides
thermal overload indication.
• A precision balance of 0.0127 mm (0.0005 in.) total peak-to-peak displacement.
• A CEI/IEC 72-1 metric flange mount with metric shafts.
• A threaded hole on the face of the shaft for securing couplings.
Note: For drive compatibility, refer to the Motor Selection Chart in Preface.
Feedback Options
1326AB servo motors are available with either resolver (standard) or high-resolution encoder feedback
devices. Resolver-based servo motors feature:
• A rugged, brushless resolver that provides accurate position feedback, eliminates the need for
on-board electronics and can withstand harsh shock, high operating temperatures, and vibration.
• Resolver feedback generates (2048ppr) A quad B encoder output. High-resolution servo motors are
available in single or multi-turn configurations that provide high-resolution encoder feedback for
applications requiring precise tolerance.
• Single-turn (-S) configuration provides precise machine positions of two million counts per revolution.
